A novel technique for determining the chemical states of elements with a heterogeneous distribution in samples involving EPMA line analysis is proposed. LLS (linear least squares) calculation was applied to a set of reduced spectra measured in the li

Sorption of CO2 in poly(methyl methacrylate) at 35−200 °C and concurrent dilation of the polymer at 35−85 °C over a pressure range up to 50 atm were studied. Dissolution and Flory−Huggins interaction parameters for the gas in the polymer, not

A membrane was produced from an ABA-type block copolypeptide composed of poly(L-glutamic acid) as outer segments (A) and poly(L-leucine) as the inner (B). The membrane had phase-separated morphology with the poly(L-glutamic acid) embedded in a contin

A membrane produced from a tri-block copolypeptide compound of poly(L-glutamic acid) as outer segments and poly(L-leucine) as an inner segment spontaneously generated electrical pulses under a concentration gradient of KCl in the absence of any exter

The copolymer [CH 2 CH(CH 2 NH 2 .HCl)] m [CH 2 CH(CH 2 NHC[=NH]NH 2 .HCl)] n has been synthesized by the reaction of polyallylamine hydrochloride with N-carbamoyl-O-methylisourea followed by thermal decomposition of the resulting poly(allyl-N-carbam

The solid-state conformation of copolymers of oxidized L-methionine [L-Met(O)] with L-methionine (L-Met) and/or L-alanine (L-Ala) was studied by IR spectroscopy and circular dichroism (CD). The results from the IR spectra in the region of 900−330 c

Three series of consolidated undrained triaxial compression tests on two saturated remoulded clays were performed to investigate the influence of duration of anisotropic consolidation up to 120 days on the undrained stress-strain behavior of clays. E

The permeability of poly-L-methionine (PLM) membrane and its oxidized form to water vapor was studied. Permeability coefficients of the PLM membrane were large, of the order of 10−7 cm3 (S.T.P.)·cm/cm2·sec·cm Hg. The sorption and permeation beha

Membranes of copoly(γ-methyl L-glutamate, γ-benzyl L-glutamate) (PMBLG) as well as the related homopolymer membranes were prepared, and permeabilities of oxygen, nitrogen, argon, and carbon dioxide were measured in the 0–70°C temperature range.
